It's wedding bells for Blake Lively and Ryan Reynolds! After approximately a year of low-key dating, the TV/movie-star couple reportedly married in South Carolina on Sunday night (September 9).

Lively, the 25 year old star of Gossip Girl, married her 35 year old Green Lantern co-star in a formal -- but super-private -- ceremony at the Boone Hall Plantation in Mount Pleasant, South Carolina, People.com reports.

Since none of this is actually confirmed, there is no definitive guest list for the wedding. But who was rumored to be in attendance? Florence Welch of Florence and the Machine apparently attended and performed for the newlyweds. Blake Lively's mother and sister were also there, having been seen in South Carolina (dining with none other than Bette Midler!) earlier in the weekend.

This superstar relationship has been noticed but muted for the past year. Lively and Reynolds did buy a home in New York together and have been spotted as a couple a few other times. Despite this, neither of the actors have publicly mentioned their relationship explicitly. They have been so secretive, in fact, that the author of this article couldn't find a photo of the couple together.

A wedding, however, is pretty obvious. Assuming anyone finds out about it, of course.

The marriage marks the first time to the altar for Blake Lively and a second-go-round for Ryan Reynolds. Lively dated her Gossip Girl co-star Penn Badgely for about two years, but the pair broke off their relationship back in 2010. Ryan Reynolds, meanwhile, married actress Scarlett Johansson in 2008. They divorced in 2010.

Considering all of the celebrity break-up news we usually get to hear, a wedding -- however private -- is kind of a refreshing change. Now at least we can try to forget about how Amy Poehler (Parks and Recreation) and Will Arnett (Arrested Development) destroyed our belief in love and a benevolent universe.

Instead, we can think about the joining of beauty brought to us by newlyweds Blake Lively and Ryan Reynolds. You know, assuming this wedding actually happened.
